Title: Reticle, electron beam exposure apparatus and manufacturing method for semiconductor device
Inventor: HASHIMOTO SUMIO
IPC: G03F1/20
Filed: 2002-03-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electron beam exposure apparatus that can expose and transfer a pattern of finer line width, as compared with an electron beam exposure apparatus of conventional conception.  <P>SOLUTION: Normally, intensity distribution of an electron beam is not of a rectangular distribution that faithfully corresponds to (a) because of diffraction phenomenon, but has a distribution containing a specified widening as in (b). As opposed to this, by using a reticle that is so formed that the phase of electrons passing through a periodical pattern on the reticle is alternately shifted by (n+1/2)λ for each unit pattern of the periodical pattern, the pattern of a distribution of the electron beam taking account of phase is, as shown in (c). Thereby, at a part where the electron beams overlap with each other corresponding to the lower slopes of adjacent patterns, both distributions cancel with each other and the intensity of the electron beams is weakened, so that, pattern will not be formed at a part where the pattern is absent.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To extract an information signal with accuracy even when a reception signal is input in a low amplitude level.  <P>SOLUTION: By setting the ratio between the gate width Wp of a p-MOS 18 and the gate width Wn of a n-MOS 20 between 1:0.9 to 1:1.1, the capacity between the gate terminal 42 and the source terminal 22 of the p-MOS 18 is set approximately equal to the capacity between the gate terminal 44 and the source terminal 24 of the n-MOS 20. Because the component of a p-channel control signal leaked through the inter-terminal capacity between the gate terminal 42 and the source terminal 22 of the p-MOS 18 is canceled by the component of a n-channel control signal leaked through the inter-terminal capacity between the gate terminal 44 and the source terminal 24 of the n-MOS 20, it becomes possible to suppress generation of an error component in a signal output terminal 12 caused by the leak component of the two control signals.  <P>COPYRIGHT: (C)2004,JPO
